Los Angeles has a rich history of muralism dating from David Alfaro Siqueiros' famed 1932 mural “América Tropical,” recently restored by the Getty Conservation Institute, to the present day, when the restoration of LA’s “Freeway Murals” is being undertaken. This public art takes many forms from gang tagging and graffiti to muralism and street art. Muralism creates a sense of place within communities and also represents a form of resistance. How does street art contribute to neighborhood revitalization? Ideally, because it challenges and transforms the viewer’s experience of their environment.
